\(25+\left(x-5\right)=-15\\ x-5=\left(-15\right)-25=\left(-40\right)\\ x=\left(-40\right)+5=-35\)
25 + (x-5) = -415 - (-400)
25 + (x-5) = -15
x-5 =-15 - 25
x-5 = -40
x = -40 + 5
x = -35
25 + ( x - 5 ) = − 15
x − 5 = ( − 15 ) − 25 = ( − 40 )
x = ( − 40 ) + 5 = − 35
25 + (x-5) = -415 - (-400)
25 + (x-5) = -15
x-5 =-15 - 25
x-5 = -40
x = -40 + 5
x = -35
\(25+\left(x-5\right)=-415-\left(15-415\right)\)
\(25+\left(x-5\right)=-415-\left(-400\right)\)
\(25+\left(x-5\right)=-15\)
\(\left(x-5\right)=\left(-15\right)-25=-40\)
\(x\) \(=\left(-40\right)+5=-35\)
